Introduction 1
1 Introduction
The PCI/cPCI/PM-7841 is a Controller Area Network (CAN) inter-
face card used for industrial PC with PCI, Compact-PCI, and
PC104 bus. It supports dual ports CAN’s interface that can run
independently or bridged at the same time. The built-in CAN con-
troller provides bus arbitration and error detection with auto cor-
rection and re-transmission function. The PCI cards are plug and
play therefore it is not necessary to set any jumper for matching
the PC environment.
The CAN (Controller Area Network) is a serial bus system origi-
nally developed by Bosch for use in automobiles, is increasing
being used in industry automation. It multi-master protocol, real-
time capability, error correction and high noise immunity make it
especially suited for intelligent I/O devices control network.
The PCI/cPCI/PM-7841 is programmed by using the ADLINK‘s
software library. The programming of this PCI card is as easy as
AT bus add-on cards.

2 Installation
This chapter describes how to install the PCI/cPCI/PM-7841. At
first, the contents in the package and unpacking information that
you should be careful are described.
2.1 Before Installing the PCI/cPCI/PM-7841
Your PCI/cPCI/PM-7841 card contains sensitive electronic compo-
nents that can be easily damaged by static electricity.
The card should be done on a grounded anti-static mat. The oper-
ator should be wearing an anti-static wristband, grounded at the
same point as the anti-static mat.
Inspect the card module carton for obvious damage. Shipping and
handling may cause damage to your module. Be sure there are no
shipping and handing damages on the module before processing.
After opening the card module carton, exact the system module
and place it only on a grounded anti-static surface component side
up.
Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your PCI/cPCI/PM-7841.

2.5 Jumper and DIP Switch Description
You can configure the output of each channel and base address
by setting jumpers and DIP switches on the PM-7841. The card's
jumpers and switches are preset at the factory. Under normal cir-
cumstances, you should not need to change the jumper settings.
A jumper switch is closed (sometimes referred to as "shorted")
with the plastic cap inserted over two pins of the jumper. A jumper
is open with the plastic cap inserted over one or no pin(s) of the
jumper.
2.6 Base Address Setting
The PM-7841 requires 16 consecutive address locations in I/O
address space. The base address of the PM-7841 is restricted by
the following conditions.
1. The base address must be within the range 200hex to
3F0hex.
2. The base address should not conflict with any PC
reserved I/O address.
The PM-7841's I/O port base address is selectable by an 5 posi-
tion DIP switch SW1 ( refer to Table 2.1). The address settings for
I/O port from Hex 200 to Hex 3F0 is described in Table 2.2 below.
The default base address of your PM-7841 is set to hex 200 in the
factory( see Figure below).
